POWER WINDOW
GENERAL DESCRIPTION I
The circuit consists of the starter switch, (door lock &) power window switch for each of the front wlndows,
power widow switch for rear windows and power window motors.
When the starter switch is
turned on, the battery voltage is applied to each of the power window switches
through the circuit breaker and the power window relay on the circuit. ,
The "DOWN" switch of the driver's power window switch has a built-in function which can be ope~ted by
just.t?uching it. Accordingly, the window will roll down automatically by just setting the switch to thf AUTO
pos1t1on. ,
When the driver's power lock switch at the driver side is depressed, the power source to the pas~enger's
power window switches are shut off. So, even if these switches are operated, the power window motor will
not operate.
